SOLDERNG IRON.

`.ippnnaumfi inea october a7, ieee. serial no. 419,941.

To all ywhom t may concern: ,j

lie it known that l, EDWARD S. Gnmnsrin, a citizen of the United States,residing Lat Chicago, in the county of Cook and citate of lllinois, haveinvented a certain new and useful improvement in Soldering irons, ofwhich the following is a full, clear, concise,

and exact description, reference being had j to the accompanyingdrawings, forming a part of this specification.v

My vinvention `relates to soldering irons and more particularly to ironsof this character which are continuously heated during use by flame.`

My invention has for its object the pro-' vision of an improved deviceof this charac-v ter which shall be simple in construction and whichshall be exceedingly light, the en` soldering tip in such manner `thatwhen using a flame comparable in some respects to the Bunsen flame, ashield 1s introduced on one side of the gas cone which shield preyventsthe gases from being ignited on that side. For this reason, the gaseswill burn on the; other side and forwardly of the gas cone. V

The flame, under these conditions, will be increased in volume onthatparticular side and will extend along the opposite sides of thesoldering tip.

will explain one form whichmy invention may take, more in detail byreferring to the accompanying drawing in which- Fig. 1 is a side view ofa soldering iron constructed in accordance with my invention;

Fig. 2 Fig. 3; t

Fig. 3 is a fragmentary side View at a 90o angle to the View of Fig. l;and

Fig. 4t is a sectional view on .line ii- 4 of Fig. 2.

My improved device includes a tube 10 over which a handle 11 is drivenso as to remain securely in place. The tube 10 at its right handextremity engages a flexible tube 12 having the coupling 13 whereby thesame may be attached to any suitable source of gas arrangement which isa sectional view on line 2-2 ofsupply. The tube ,10 has at its left handextremity aconipound curve as at 14 ending in an orifice 15. The extremetip ofthe tube forms a detlector "1G `which considerably overhangs theorifice 15. rlhetube 10 carries near its left hand. extremity a 'shell17 which shell or tubehas 'a portion of its left hand extremity cutawayas shown at 11S, forming a trough within which the soldering `tip 19 ismounted and held in place by means of the screws 20-20. The shell 17 lis se-V curely mounted upon the tube 10`as is readily apparent. A hole20a is drilled entirely through the opposite walls of the tube and shell1T and the degree of opening of this hole is controlled by theadjustable split sleeve 21. This adjustable sleeve `is slotted or splitat one side as shown more clearly in 7ig. 1 and has on its oppositeside, 'a hole 2; '.llhus, when the sleeve isin the' position 'hown inthe illustrations,` the holes 2Gl the opposite 'walls of the parts 10and 17 are entirely open. The sleeve 21 is springy or` resilient so thatit remains in the position in `which it is set. ltmay be rotated awayfrom theposition shown in the illustrations to more or less close thedegree of opening permitted through the holes 20a. This regu- .lates theair supply to the. interior of the tube 10.'

N ow one of the main objects of the invention is to provide a structureof such a nature that the gas yas supplied through the tube. 10, ismixed with the air entering through the holes 20a and that this gas whenignited, forms a flame at the orifice 15 which is directed against thetip 19 by the de- Hector 16.

While this structure general may follow the broadlines of the yBunsenburner,

yet the arrangement of the parts is such that instead of having `thegases burning on all sides and forward of the gas cone, the gases areallowed to burn only on one side and forward of the gas cone. In thismanner, l secure a high heating effect because of the concentration ofthe flame upon the soldering tip. This arrangement allows the burner tobe fastened much closer to the soldering tip than if an ordinary burnerwere used, which burner would have to be placed at an angle to properlydirect the liame against the soldering tip. This improved burner,therefore, has the advantage of forming a more compact and neater tool.

lItwill be noted that the Structure is of extreme simplicityV and thatthe various tubes', shells and sleeves together with thel handle 11, fiteasily together and are easily y `held in place.

I thus secu'revthegreat advantage of having an extremely light structurefor the soldering iron. In order vtoV direct the flow kof gas inaccordance with the invention, I provide a plug 23 having a smallhollowbore l24l,which plug is forced into position-.within the tube I0and which forms i i Aa sort ofnozzle to directtheliow of thegas withinthetube l() and "to give the gas vsufficient velocity to draw lairin"through the holes to mix with the gas.

From what has been thus described, it is thought the nature of myinvention will' be readily clear to those skilled in the art.
